Description

It is a kind of to be integrated and connected joint for multiple spot gas pressure pipeline
Technical field
It is more particularly to a kind of to be integrated and connected joint for multiple spot gas pressure pipeline the present invention relates to a kind of joint.
Background technology
, it is necessary to test a large amount of gas pressures during engine test, to ensure gas pressure response speed, gas pressure Measurement is needed as close to gas pressure point position.In view of economy and technical problem, during usual engine assembly, The gas pressure of required measurement is drawn into engine using pressure guiding pipe, impulse pipe end welding pressure joint, before engine test, Engine gas pressure is forwarded to test system by tester using stainless steel pressure pipe from joint.Engine gas pressure is surveyed Point up to up to a hundred, needs to connect a large amount of gas pressure pipelines, this one-to-one single-point wiring in engine test set-up procedure Mode efficiency it is low, it is necessary to fastening joint it is more, fault rate is higher.
The content of the invention
The purpose of the present invention:Engine gas pressure line joint efficiency can be improved by providing one kind, reduce joint quantity, The multiple spot gas pressure pipeline for reducing gas pressure pipeline connecting fault rate is integrated and connected joint.
Technical scheme:It is a kind of to be integrated and connected joint for multiple spot gas pressure pipeline, it is characterized in that:Described Joint includes preceding tail attached 1, gas pressure import 2, preceding pressure tight joint 3, seal washer 4, rear pressure tight joint 5, gas Pressure export 6 and rear molding attached 7, preceding pressure tight joint 3 is separately installed with preceding tail attached 1 and rear molding attached 7 and rear pressure seal connects First 5, it is right that gas pressure import 2 and gas pressure export 6 are separately mounted to preceding pressure tight joint 3 and rear pressure tight joint 5 On the position answered, seal washer 4 is respectively arranged between preceding pressure tight joint 3 and rear pressure tight joint 5.
One kind as the technical program is improved, and gas pressure import 2 and gas pressure export 6 include the He of pedestal 8 respectively Waist drum pipe 9, waist drum pipe 9 are arranged on pedestal 8, groove are provided with pressure tight joint (3,5), through hole, gas are provided with groove The pedestal 8 of pressure inlets 2 and gas pressure export 6 is installed in the groove, and sealing gasket is provided between pedestal 8 and groove floor Circle.
One kind as the technical program is improved, and passage 10 is provided with preceding tail attached 1 and rear molding attached 7.
Beneficial effects of the present invention:Multiple spot gas pressure pipeline can be quickly connected, improves gas pressure pipeline connection effect Rate.Reduce the joint that needs fasten, reduce gas pressure fault rate.
Brief description of the drawings
Fig. 1 is the part drawing of the present invention;
Fig. 2 is that gas pressure enters and (gone out) mouth structure schematic diagram;
Fig. 3 is pressure tight joint structural representation.
In figure:1 is that preceding tail is attached, and 2 be gas pressure import, and 3 be preceding pressure tight joint, and 4 be seal washer, 5 be after press Power seal nipple, 6 be that gas pressure exports, and 7 be that rear molding is attached, and 8 be pedestal, and 9 be waist drum pipe, and 10 be passage.
Embodiment
It is a kind of to be integrated and connected joint for multiple spot gas pressure pipeline, it is characterized in that:Described joint include preceding tail it is attached 1, Gas pressure import 2, preceding pressure tight joint 3, seal washer 4, rear pressure tight joint 5, gas pressure outlet 6 and rear molding are attached 7, preceding pressure tight joint 3 and rear pressure tight joint 5, gas pressure import 2 are separately installed with preceding tail attached 1 and rear molding attached 7 It is separately mounted to gas pressure export 6 corresponding to preceding pressure tight joint 3 and rear pressure tight joint 5 on position, preceding pressure Seal washer 4 is respectively arranged between seal nipple 3 and rear pressure tight joint 5.Preceding tail is attached 1, rear molding attached 7 is close by preceding pressure Sealing joint 3, rear pressure tight joint 5 connect, and global shape is fusiformis after the completion of connection.
One kind as the technical program is improved, and gas pressure import 2 and gas pressure export 6 include the He of pedestal 8 respectively Waist drum pipe 9, stomata being provided with pedestal 8, waist drum pipe 9 is arranged on the stomata of pedestal 8, and pressure tight joint is provided with groove on (3,5), It is provided with through hole in groove, the pedestal 8 of gas pressure import 2 and gas pressure export 6 is installed in the groove, pedestal 8 and pressure Seal washer is provided between seal nipple (3,5) groove floor.After installation, waist drum pipe 9, the stomata of pedestal 8, pressure seal Joint (3,5) groove inner via hole forms a gas passage.
One kind as the technical program is improved, and passage 10 is provided with preceding tail attached 1 and rear molding attached 7.Air vent 10 uses 300~800KPa gas quenchings, for preventing high-temperature gas enters multiple spot gas pressure pipeline from integrating fast connecting joint Damage internal gas pressure pipeline.
Assembling sequence during use is as follows:
Step 1:The gas pressure pipe of identical range is connect with integrated quick be connected of same multiple spot gas pressure pipeline Head gas pressure import 2 connects, and gas pressure import 2 is connected with preceding pressure tight joint 3, with the attached 1 pair of gas pressure pipe of preceding tail Road collection fasciculation and fixation;
Step 2:The gas pressure Data Acquisition Channel of identical range and same multiple spot gas pressure pipeline is integrated fast The fast connection of jointing gas pressure outlet 6, gas pressure outlet 6 is connected with rear pressure tight joint 5, with the attached 7 pairs of gas of rear molding Body pressure piping collection fasciculation and fixation;
Step 3:When gas pressure pipe connects, the preceding pressure tight joint 3 of same range is pressed with rear using seal washer Power seal nipple 5 is connected, you can completes the integrated quick connection of multiple spot gas pressure pipeline.
